here's what I did with a prolapsed vent. It's not the same, but might help?
(see my post "Help chicken's insides coming out (photo)":
"Update: After a couple of days she seemed all right, and I let her go back in with the others. She seems to be recovering quite well and I will keep an eye on her and see if this recurs.
So for anyone else in this situation, for what it is worth:
I rinsed the prolapsed area with warm water, and put honey on the area, several times, the next day washed her again and put a high quality naturopathic calendula cream on the area (gentle, for lubrication and healing), and kept her separated until she seemed better and well enough to go back in with the others. Oh and I put just a little apple cider vinegar in her drinking water. And gave her time.
Thanks for everyone's help!"
Also chicks absorb the yolk through their rear, when in the egg. Maybe he will still absorb these guts into himself if given a little time?
